摘要：近年来,中国林产品对外依存度不断提高,并且远远高于发达国家和发展中国家的水平。要科学合理地评价对外依存度,需要采取适当的比较对象并选择合理的评价指标体系。文中以18个主要国家的对外依存度为研究对象,依据整体性、科学性和可操作性等原则建立评价指标体系,借助SAS软件,先对影响对外依存度的各项指标进行因子分析,计算各主因子得分和综合因子得分并进行排序,然后在此基础上做聚类分析,将18个主要林业国家分为4类。
China＇ s foreign trade dependence of forest product has been increasing in recent years and much higher than those in developed and other developing countries. However, in order to evaluate the foreign trade dependence scientifically and reasonably, it is necessary to adopt appropriate countries and reasonable evaluation index system. With 18 forestry countries as its research object, this paper set up an evaluation index system under the principles of integration, science - based and operability. After the factor analyses were conducted for various indexes that influence the foreign trade dependence and the scores of various main factors and comprehensive factors were calculated and arranged in order by means of SAS software, the cluster analyses was made to categorize the 18 forestry countries into 4 categories.
